T0 all-whom it may omwmm: v s Be it known that I, 'Ronnu'r Sonoama citizen of the United States, and a resident of Jersey City, county of Hudson, and State of New Jersey, have invented' certainnew.

and useful Improvements in Closures for Bottles, Jars, and Sin'iilar Receptacles, of which the following is a speciiication.-

This invention relates. to closures for bot tiles, jars and similar receptacles and has for its primary object to provide acl'osure which can: be easily and: quickly applied to tightlyseal the mouth of the bottle or jar, af-

fending a complete protectionto thejcontents thereof and whlch, after it is once applied, cannot be removed and then replaced without detection views: v p I Figure 1 71sa side elevationof a portion ar provided with my new It isnai further object of my present improvements to provide a bottle or '3 ar closure ofthe above character whichmay be inexpensivelymad'e from sheet metal, and can be readily constructedin various sizes for application to bottles, jars or otl else 015, numerous shapes or forms.

litlr, the above and other objects, in view, the invention resides in the improved receptiacle closure and in the form, construction ier receptaand relative arrangement of the several parts as may be hereinaftermore fully described, illustrated; invthe accompanying drawings and subsequently incorporated in the subjoined claims. .c

In the-drawings wherein I have illustrated one-practical and satisfactory I embodiment ofth'e-invention and in which similarreference characters. designate corre-' sponding parts throughout the several V poses of -illustration,I have shown, the closure device as appliedto a bottle or jar at; eylindneal form though it willbe understood as the, description; proceeds that the onosunn FOR BOTTLES, ARS, AND SIMILAR REonrTAoLEs.

device is also applicable to receptacles of othershapes and constructed of glass or other materials. For the purposes of this description, it will suffice tostate that the body 5 of the bottle o-rreceptacle is provided at its upper end with the usual contracted neck 6, the mouth 7; on the upperend of said neck being provided with an externa annular shoulder 8. p v

The improved closure consists of a sheet metal cap 9' formed a suitable stamping operation to; provide a marginal flange or rim IOeXtendingat right angles to-the plane of the body wall of said cap. Against the inner face of this body Wall within the rim or flange 10, a disc of cork", cardboard, or

other 1 compressible material 1 1 is 7 arranged, and the lower face of this disc is coveredgby a sheet of paper; 12' which is glazed; para-fant or impervious.

Ad acent to the rim 10 0f the bottle cap,

.finechor otherwiserendered moisture resistannular indentation 13, said indentation bemg formed in a suitable machine which also produces an annular rib, or head 14 on the lower face of thedisc 1-1 and papersheet 1'2,

VVhen: thev cap is applied this ribis: located immediately within the wa ll 'of the mouth 7 of the bottle and resists lateral shifting of the bottle cap and undue strain-upon the marginal fiangeldthereof.

The-cap flange 10 is formed at cally oppositepointswith the tongues or'extensions 15 extending in the plane of' said flange and terminating the inwardly turned reinforcingbeads 16. Adjacent the bead 16. of each tongue, a horizontal" slot 17 istcutx' in the: tongue and terminates adjacent the oppositeverticalvedges thereof,

will be obvious, therefore, that-the structure of the tongue is materially weakened contiguous to the bead 16;

rim 1,0, untilthe beads 16am positioned below; the shoulder 8, when the said tongues will spring inwardly to their normal positions, the beads 16 fitting snugly against the face of said shoulder. Thus it will be apparent that the cap or closure is securely retained in its applied position against shifting movement or possible a ccidental detachment. It is important in thosecaseswhere thepurity of the contents of the' bottle'or receptacle is guaranteed by the manufacturer that it should be impossible to remove the cap or closure without detection, whereby the purchaser can be assured that he is obtaining the original unaltered product. .My present invention provides such means for insuring the immediate detection of the removal of the cap or closure. Thus, if the attempt is made to release the clamping or holding tongues, upon pull ing or prying outwardly on the beads 16, the narrow weak section's-ofthe metal 18 at op posite ends of the slot 17 will immediately yield since thebead is relatively stiff or Thus these narrow metal portions will be broken in the removal of the clamping tongues and it will be impossible to replace thetongues in their original condition so that the cap or closure could be again ap plied to the bottle without immediate de tection that it had been removed since the bottle was originally sealed.

In Figures 3 and t of the drawings 1 have illustrated another form of the device in which the clamping or gripping tongues on the bottle cap are not provided with the slots 17 In this case, therefore, the lower ends of the tongues having the ribs 16 will not be broken off when the attempt is made to remove the bottle cap. However, an indicating means is provided in the form of an annular or'circular sheet of light soft metal 19 such as tinfoil. The bottle cap at the juncture of its rim and body portion has an annular inclined or beveled section to which the edge 20 of the metal sheet/19 is permanently and securely fixed in any suitable manner. This sheet of soft metal is in close contact with the rim and the tongues of the bottle cap and is of greater width than the bottle cap so as to provide an annular skirt portion 21 extending downwardly below the tongues and preferably in engagement at its lower edge upon the body wall of the bottle. Thus access to the tongues 15 is prevented and in order to engage the ribs 16 on said tongues with the fingers for the purpose of removing the bottle cap, it is first necessary to tear away the skirt portion 21 of the soft metal band or sheet 19. Obviously, when this metal band is thus torn or mutilated, it cannot subsequently be again restored to its original condition. Thus the purchaser will immediately observe that since the original contents was placed in the bottle by the manufacturer, said bottle had been opened bythe removal of the closure cap.

From the foregoing description considered in connection with the accompanying drawing, theconstruction, manner of operation and several advantages of my invention will be clearly and fully understood. It will be seen that the device herein described is very effective for the purpose in view, and as the bottle caps canfbe readily produced in large quantities by' a simple stamping operation the article may be manufactured at small" cost. herein disclosed several forms of the device which I have found to be very satisfactory in practical use but it will nevertheless be understood that the improved bottle closure I have might also be produced in various other '1 alternative forms and I, therefore, reserve the privilege of resorting to all such legitimate changesin the form, construction and relative arrangement of the several parts as may be fairly embodied within the spirit 1 and scope of the invention as claimed.

In Figure 6 of the drawing I have illustrated a closure cap produced from comparatively non-resilient metal having the tongues 15 initially extending outwardly at an angle from the edge of the marginal flange 10. Thus it will be understood that after the cap has been applied over the mouth of the bottle or jar, suitable means is employed'to bend or force the tongues 15 inwardly so that they will extend in the plane of the marginal flange 10, and thereby position the beads 16 on the free ends of said tongues beneath the annular shoulder on the neck wall of the vessel or container. i i

I claim: 7

1.-A closure for receptacles comprising a cap adapted to be fitted over the mouth of the receptacle and having integral clamping devices for engagement with a shoulder on the receptacle wall, said cap being also provided with sealing; means for the clamping devices comprising an annular skirt of soft metal secured to the upper edge of the cap fitting the circui'nferential portion of the cap and extending over said clamping devices to prevent the unauthorized removal of the cap by manipulation of said clamp-- ing devices.

A. closure for receptacles comprising a cap adapted to be fitted over the mouth of the receptacle and having an annular rim portion provided with resilient tongues each having a gripping element on its free end for engagement with an annular shoulder on the receptacle all, each of the tongues being provided with relatively weakened portions adjacent to the gripping element and beyond the confines of the cap whereby the gripping elements at such weakened portions will break off from' the lower end of the tongue upon the attempt to disengage the gripping elements from said shoulder in the removal of the cap from the bottle, andthereafter the remaining portion of the tongues are adapted to yield ingly engage the receptacle for removably holding the cap thereon,

3. A closure for receptacles comprising a cap adapted to. be fitted over, the mouth of the receptacle, said capliaving an annular rim provided with a plurality of extending resilient tongueseach terminating in a gripping element adapted for engagement with a shoulder on the receptacle Wall, each tongue having a slot cut therein beyond the confines of the cap in parallel relation to the gripping element and providing relatively' weakened portions in the tongue at the opposite ends of said slot, whereby the gripping elements at such weakened portions of the tongue will yield and break off from the lower end of the tongue upon the attempted disengagement of the gripping elements from said shoulder to effect the removal of the bottle cap and thereafter ROBERT SORGAN.
